An experiment was conducted at Krishi Vigyan Kendra, Hoshangabad (MP) during Kharif season year 2014 and 2015. The experiment comprising of seven weed management practices in main plot and 4 fertility levels in sub- plots with 3 replication at KVK field. As per pooled data Increase in seed yield by two hand weeding at 20 and 45 DAS, Imazamox + Imazethapyr @ 75 g(a.i.)/ha, Imazethapyr @ 100 ml(a.i.)/ha at 18 DAS, Pendimethalin @ 1.0 lt.(a.i.)/ha + 1 HW (35 DAS), Quizalofop-ethyl @ 50 ml. (a.i.)/ha and Clodinafop-propargyl 60 @ g (a.i)/ha was 2198, 2020, 1956, 1895, 1649 and 1525 kg/ha higher, respectively over weedy check. 2 hand weeding registered highest soybean straw yield (3235 kg/ha) followed by Imazamox + Imazethapyr @ 75 g (a.i)/ha (3052 kg/ha), which were significantly superior over weedy check. Among the fertility levels, application of 100 and 125 % N, P2O5, K2O along with sulphur significantly influenced yields of soybean over 100 % N, P2O5, K2O, both of these maximized the seed yield (1755 and 1790 kg/ha) and straw yield (2723 and 2760 kg/ha) over 100 and 125 % N, P2O5, K2O without sulphur.
